/**

|
* Specifies that a persistent property or field should be persisted
|
||
|
|
* as a enumerated type. The <code>Enumerated</code> annotation may
|
||
|
|
* be used in conjunction with the <code>Basic</code> annotation, or in
|
||
|
|
* conjunction with the <code>ElementCollection</code> annotation when the
|
||
|
|
* element collection value is of basic type. If the enumerated type
|
||
|
|
* is not specified or the <code>Enumerated</code> annotation is not
|
||
|
|
* used, the <code>EnumType</code> value is assumed to be <code>ORDINAL<code>.
